GEORGE Gr. FLOYD, OF CHICAGO, ILLINOIS, ASSIGNOR 'IO AMERICAN STEEL FOUN- DRIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

CONNECTION BETWEEN SIDE FRAMES AND TIE-BARS.

Application filed April 8,

872,222, filed April 8, 1920, I have disclosed a truck side frame arrangement in which the tie bar is pivotally connected to the tension member of the truck side frame. In this present application I have disclosed a modified arrangement in which the journal box tie bar is permanently secured to the truck side frame.

The object of the invention is to provide a tie bar and means for securing the same 'to the truck side frame in a manner to meet the various commercial requirements,

This and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which Figure 1 is a truck side frame embodying my invention;

Fig. 2 is a fragmentary top plan view showing the connection between the tension member of the truck side frame and the journal box tie bar; and,

Fig. 3 is a sectional view taken in the plane of line 3-3 of Fig. 2. I

Referring first to Fig. 1 of the drawings, it will be noted that Ihave shown a truck side frame having a tension member 10, compression member 11, columns 12 (only one of which is shown), and a journal box receivin portion 13, all cast in a single piece. In this particular case thetension and compression members are of channel section and have their webs 14 and 15 at the upper sides, respectively, of said tension and compression members, said webs 14 and 15 being connected to each other at the point 16 over and slightly outwardly with respect to the inner ournal boxbolt 17. This inner Specification of Letters Patent.

journal box bolt 17 and the outer journal box bolt 18 pass downwardly through openings 19 and 20 in a journal box receiving flange, and also through the associated journal box lugs 22. 23, 24: and 25. Said bolts 17 and 18 also pass through openings in the journal box tie bar 26, the lower ends of said bolts receiving washers 2'7 and nuts 28. This tie bar has two portions extending at an angle with respect to each other, one portion being secured to the journal box and normally being in a horizontal plane, while the other portion extends at an angle to the horizontal and has an enlarged portion 29 near one end which terminates in a T-shaped head 30 or an end which has two oppositely extending legs 31 and 32. This T-shaped head is permanently secured to the web 14: of the tension member by rivets 33 and 3e, thereby providing a secure connection for the journal box tie bar and one which is adapted to meet all of the service requirements.

By providing this connection between the tie bar and side frame, the use of a tie bar bracket is obviated. Such tie bar brackets cast integrally with side frames as used heretoforeare objectionable to a certain extent in that there is a tendency for the metal to shrink .or crank around the juncture of the bracket and the frame; also the average tie bar bracket adds from fifteen to sixteen pounds to the side frame, while the connection which I have provided at most adds only three or four pounds to the weight of the side frame.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claim.

I claim:

In combination, a truck side frame having a tension member of channel section with a webportion, and a journal box tie bar having a T-shaped head extending into thejochannel and permanently secured to said we Signed at Chicago, Illinois, this 24th day
